# std::fgetc, std::getc

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cstdio>` |  |
int fgetc( std::FILE* stream ); int getc( std::FILE* stream ); |  |

Reads the next character from the given input stream.

### Parameters

stream | - | to read the character from

### Return value

The obtained character on success or EOF on failure.

If the failure has been caused by end of file condition, additionally sets the eof indicator (see std::feof()) on stream. If the failure has been caused by some other error, sets the error indicator (see std::ferror()) on stream.

### Example

Run this code

    #include <cstdio>
    #include <cstdlib>

    int main()
    {
        int is_ok = EXIT_FAILURE;
        FILE* fp = std::fopen("/tmp/test.txt", "w+");
        if (!fp)
        {
            std::perror("File opening failed");
            return is_ok;
        }

        int c; // Note: int, not char, required to handle EOF
        while ((c = std::fgetc(fp)) != EOF) // Standard C I/O file reading loop
            std::putchar(c);

        if (std::ferror(fp))
            std::puts("I/O error when reading");
        else if (std::feof(fp))
        {
            std::puts("End of file reached successfully");
            is_ok = EXIT_SUCCESS;
        }

        std::fclose(fp);
        return is_ok;
    }

Output:

    End of file reached successfully
